To all whom t may concern.'

Be it known that I, CHRISTIAN A. MAR- soHnL, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Typewriting chines, of which vthe followingis aspecilication,

This invention 4relates to typewriting machines, and is herein disclosed-as applied to an Underwood standard typewriting machine Vof the continuous billing or yso-called fan-fold type, one form of which is disclosed in the 4patent Lto Vernery & Smith, No. 1,132,055, dated March 16, 1915.

In such machines, a plurality of plies of superposed webs, either` fan-folded or not, are drawn over a rearward extension of the usual typewriter carriage, and pass beneath the platen, being threaded through carbon-paper-holding devices which are supported on the extension.

ln such n'iai'fnines, the platen is displaceable to enable webs passed beneath it'to be drawn forward substantially straight loeneath the platen when the platen is in its displaced position, so that .the webs may be gaged against a `leading-edge gage and the carbons or carbon-sheets may be withdrawn by moving their supporting devices rearwardly along the extension. n Such machines also usually include a knife located adjacent the printing line, but 4somewhat above it, the relationship of vthe carbonsheets and the knife being such that after the webs have'been gaged, and the supporting devices pushed' rearwardly, the carbonsheets lie behind the cutting edge of the knife, thus enabling the webs to be severed without interfering withthe carbon-sheets.

Such machines are often yused for simultaneously making copies oflbills, statements, way-bills, bills of lading, dray-bills, etc. It is often desired, in making out such simultaneous copies, to have all theentries and extensions appear upon thebill, while only the heading, or only Ithe heading and certain other entries, should appear on certain of the other copies.

According 'to' the present invention, the arbon-paper-supporting devices, which vusually form a single carriage or carrier, are di ideal, being made intov two carriages or carriers ywhich may 4'he separately moved, thus enabling one set of carbon-sheets to be withdrawn kby oneof the carbon-paper-carriarges after :the work-sheet has 'zbeen partly typed, while the other carbon-paper-carriage is left undisturbed, thus permittingxthe carbon-sheets on the last-,named carriage to reproduce the whole ofthe matterftyped upon the outer sheet. The ltwo lcarbon-paper-car- :riages may .run uponthe usual single Iset 0f rails, and each carriage `may have associated therewith an independentlyadjustable Ystop Ifor arresting it. Each of thecarbon-paper- Y Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure@ is a View similar to Figure 5,

but showing the position oflthe parts after the bill or other work-sheet has been fully typed. Y t

Figure 7 is a view similar to Figure 6, but

showing the webs gaged against the leading-r typewriter carriage 16, passing beneath the platen 17, and up in front, past the printing point at the type-bar diagrainlnatically shown at 18, to a front paper-table 19..

The Webs 10, 11, 12 and 13 have threaded between them carbon-sheets 20, 21 and 22, the first sheet 2O being supported upon a rear carbon-paper-carriage 23, and the carbon-sheets 21 and 22 being supported upon a front carbon-paper-carriage 24; These carbon-paper-carriages may, in v many respects, resemble the carbon-paper-carriage of said patent, or the carriages of the machines now in use, in which each carriage comprises a body 25 having successively higher steps or bases 26 thereon, upon which carbon-paper clip-bars 27 are adapted to be detachably held fast by pins 28. The bases -26 of the rear carriage 23 are successively higher than the highest step 26 of the front carriage 24. The carriages 23 and 24 are shown as provided with rolls 29 which run upon the edges of rails 30, which form part of the extension 15, and are united by the cross-bar 14.

lVhen the parts are in the Figure 1 position, the carbon-sheets all extend slightlyV above Vthe printing line at 18, and the typist may write the heading or other desired matter uponaform on the outer sheet or web 13 by actuating the type-bars 18 through the usual keys, not shown. After each line is written,

the typist actuates the usual line-space lever Y 31, which is effective on the line-space wheel 32 to rotate the platen 17 by means of the usual gears 33 and 34. After all the heading has been typed and it is desired to type on the rest of the form matter which shall vappear only upon the two outer carbon copies, the typist seizes the webs 10, 11, 12 and 13,which have now reached the Figure '4 position', and, while holding them against the front paper-table 19, actuates the usual finger-piece 35 to free the swing-frarne 36 from the'usual catch 37, and swings the swing-frame 36 forwardly, lifting the platen 17 to the Figure 5 position. This straightens out the webs and enables the typist to push rearwardly, to the Figure 5 position, the rear carbon-paper-carriage 23 by pushing upon its handle 38 which extends forwardly to about the usual position of such handles.

Xtent of such rearward movement is sufficient to withdraw the forward end of the carbon-sheet 20 to the rear of the lower end of the form being typed, and is substantially the same as the length of a forni. Then the typist throws the swing-frame 36 rearwardly, so Vthat it catches beneath the catch 37, and the typist continuesV to type upon the cuter sheet and the two outer carbon-sheets. During this latter typing, the carbon-sheet 26, which is attached to the carbon-papercarriage 23, is fed forwardly with the webs Vand the carbon-sheets 21 and 22 until the carbon-paper-carriages 23 and 24 reach their figure 6 positions.

Then the typist has finished all the typing to be done upon the form now being typedLso that the partsy have reached the Figure 6 position, the typist again actuates It should be understood that the the finger-piece 35 to release the catch 37,

and swings the swing-frame 36 upwardly, and gages the leading ends of the webs against the usual adjustable leading-edge gage 39, which is adjustably mounted upon the usual extension 40 of the front papertable. This may drag the front carbon-paper-carriage' forwardly until the front end thereof strikes some part of the main typewriter carriage 16, and the typist, continuing the pulling upon the webs, pulls the rear carbon-paper-carriage or carbon-carrier 23 forward until the webs arey gaged. Consequently, when the front carbon-paper-car riage 24 is pushed rearwardly by its handle 41 the whole length of one form in the usual manner, the two carriages come together before the front carbon-paper-carriage 24 strikes the adjustable stop 42, positioned in accordance with the length of the 'forms on the webs 10,11, 12 and 13. The forward ends of the carbon-sheets are thus restored -to their proper alignment which is maintained during Vthe movement of the carbonpaper-carriage 24 to its Figure `7'position.

Tn order tok enable the rear carbon-papercarriage 23 to pass the stop 42, said stop is in the forni of a hook having a fiat top 43 adapted to overlie the rail 30, and having a hooked end 44, which embraces the rod 45 Aforming the stiffener for the rail 30. For adjusting the stop 42, there is provided a thumb set-screw 46 passing through it and adapted to.l bear against the: rod 45, so that the flat top 43 is drawn down against the rail 30. To enable the carriage 24 to be arrested by this stop, said carriage is provided Awith a lug 47 on the bottom of its body 25, which lies beneath the body and above the adjacent rail 30. i

Tn order to relieve the mind of the typist of having to Aobserve the distance to which the rear Ycarbo-n-paper-carriage 23 should be pushed by its handle 38 in bringing it 'to the Figure 5 position, there isY provided a stop 18, which is shown as adjustable along the left-hand rail of Figure 3, and which is adapted to be held Kin'position along 'that rail by a thumb-screwv-lQ. The stop 48 may project to any desired eXtentabov-e its adjacent rail 30, and may comprise legs 50, which extend beneath the edges of the rail 30, and are adapted to catch that rail and hold lthe stop in positionupon the rail. The-body y51 of the stop projects far enough abovefthe rail to be struck by the rear end of the body 25 of the carbon-paper-carriage ,Vhen the typist has tinished'the ityping of the forms and has gaged the forms, as shown in Figure 7, and drawn the 4 swingframe 36 back to the Figure l position, it is customary to sever the webs 10, 11, 12 and 18 by drawing them against the usual knife 52, which is somewhat above the printing line, although adjacent it. rhe stop-42 is so positioned relativ-ely to this knife that when the carriages are brought 5to rest with the stop 42 effective, the carbon-sheets 20, 2l and 22 occupy the Figure l position,-so that the webs may Ibe detached by drawing them against the knife 52 to sever vthem without severing the carbon -sheets This leaves the webs and carbon-sheets.positioned as in Figure l., ready for typing the next form.

The machine described `is 4not `limited in use to the particular mode of `operation hereinbefore set forth. yFor example, one fan-fold web may be interleaved with the carbons of the carbon-paper-carriage QSand another fan-fold web may be interleaved with the carbons of the carbon-paper-carriage 24;, and either of these webs may be typed upon to the exclusion ofthe other by simply withdrawing the endof the web which is to be idle with its interleaved carbons from around the platen and laying it back upc-n its carbon-paper-carriage. lith this arrangement-the two websmay also be typed upon together, when desired, by `feeding them to the platen :in superposed relation. n

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
